There will be no doubles & I have money back guarantees, so there is little risk here. I specialize in unread, unopened high grade copies & lifetime collections. As such, Most books will be high grade copies. The price of this auction is the price of 110 unread comics back to the 70's including Nova #8-10, Marvel Premiere #35-36,... Most of the other books are superhero books. I take the time to sort out better copies for Buy It Now purchases .Did you know Ebay is now charging 10% on your shipping after PayPal already charges 5%? Shipping includes $2 handling to cover the cost of reimbursements, boxing & shipping. I can combine shipping & expensive additional singles can be mailed for almost free. Anyone who buys an auction should take a look at the singles I offer free shipping on before paying. Max savings is media mail shipping on about 300 comics for $23 on a mailed payment in the U.S. Batches of 110 will stuff a flat-rate box for foreigners.
